Rilu-elu Belu-be, a Bilusaludo major and military instructor within the United Earth forces aboard the *Aratrum*, operates under Commander Halu-elu Dolu-do. His purple eyes, quill-like facial growths, and distinct cheek features set him apart from his species, complementing his reserved demeanor. Stationed at Earth’s landing site during initial reconnaissance, he defends the camp against Servum assaults alongside Colonel Eliott Leland, witnessing Godzilla’s catastrophic emergence and the landing ship’s destruction.

After Leland’s demise, Belu-be spearheads hover bike fleets in Haruo Sakaki’s revised plan, maneuvering through fuel shortages and Servum disruptions to lure Godzilla Filius into a trap. His tactical precision aids in temporarily immobilizing the creature. Shifting to technological operations post-encounter with the Houtua tribe, he and Mulu-elu Galu-gu unearth nanometal arrowheads, reigniting his fervor for Bilusaludo engineering. Championing Mechagodzilla City’s reactivation, he embraces assimilation with nanometal as a collective evolutionary imperative, clashing with Haruo’s resistance.

During the final clash against Godzilla Earth, Belu-be pilots a Vulture mech to divert the creature’s attention, his frustration escalating as Haruo sabotages assimilation efforts. In a desperate bid to protect Galu-gu, he intercepts Haruo’s strike, crashing his Vulture into the ruined command center. Nanometal corruption claims his life, his final scream preserved in Mechagodzilla City’s data logs. His arc—from dutiful officer to radical proponent of technocratic supremacy—embodies the Bilusaludo ethos of sacrificing individuality for technological unity, aligning him with adversarial agendas in humanity’s struggle for Earth.
